Solve the proportion. I need to show much work so a step by step explanation would help!
kkurt [141]

Answer:

<em>Solution: x=5</em>

Step-by-step explanation:

<u>Equations</u>

This is an equation in the form of a proportion or ratio:

\displaystyle \frac{2}{x+3}=\frac{5}{4x}

To solve it, we eliminate the denominators by multiplying by both of them.

Multiply by (x+3)(4x):

\displaystyle (x+3)(4x)\frac{2}{x+3}=(x+3)(4x)\frac{5}{4x}

Simplify both sides:

(4x)*2=(x+3)*5

Operate:

8x=5x+15

Simplify:

3x=15

Solve for x:

x=15/3=5

Solution: x=5
